[jboss-jira] [JBoss JIRA] Closed: (JBRULES-1481) Stop actionQueue recursion in working memory

Stop actionQueue recursion in working memory -------------------------------------------- Key: JBRULES-1481 URL: http://jira.jboss.com/jira/browse/JBRULES-1481 Project: JBoss Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 4.0.4 Reporter: Edson Tirelli Assigned To: Edson Tirelli Fix For: 4.0.5, 5.0.0-M1 ---Efficient Queue--- 1. Change AbstractWorkingMemory.actionQueue to LinkedList and use the Queue interface. 2. AbstractWorkingMemory.executeQueuedActions change it to get the item from the queue - rather than the current list.remove( 0 ) which is causing a lot of array copies in the ArrayList. ---Stop Re-entrant queue evaluation--- 1. Add boolean evaluatingActionQueue. 2. Have the AbstractWorkingMemory.executeQueuedActions method check if true, if so then return - i.e. don't evaluate the queue, as we are already iterating it. 3. If not set to true and iterate the queue until empty, before executing set back to false.
